What is ACT?
ACT stands for Acceptance and Commitment Therapy, or Training, the most modern, science-based psychotherapy. ACT uses simple, effective and proven skills to feel better and LIVE better. All of our Brisbane Psychologists are ACT experts.

How can ACT help?
ACT is about learning proven skills to help us be the kind of people that we want to be. In the same way that you can learn to cook, ride a bike or fly a spaceship you can learn to live a more meaningful life. ACT skills allow you to live life more in touch with what’s important to you. Be present. Open up. Do what matters.
